This is a lightweight 20ga A5 made in 1966. The barrel should be marked for 2 3/4 shells. ***If the barrel is marked for 3" shells then it is not the original barrel. It is not safe to shoot 3" mag shells with the standard receiver.
Your Browning Light Weight 20ga auto-5 shotgun which was made in Belguim by FN for Browning in 1964 will have a value of between 460-600 dollars for a shotgun with the plain barrel,and a remaining finish of between 60%-90%.If you have a vent rib barrel 20ga.then the value would be between 575-850 dollars for a shotgun with the same percentage of original finish as quoted above.
Only the "light" Twenty" had a gold trigger. My 1964 Belgium Browning Light Twenty has a gold trigger.
